Abstract
A membrane separator comprising a membrane is used to separate various streams in processes for separating aromatic hydrocarbons from non-aromatic hydrocarbons. Such streams can be a lean-solvent stream, a rich-solvent stream, or a hydrocarbon stream comprising both aromatic and non-aromatic hydrocarbons. The membrane separator is advantageously used in combination with an extraction sub-system including a liquid-liquid distillation column and/or an extraction distillation column.
